Resumo: | Abstract We investigate a three-dimensional (3D) reciprocal invisibility cloak with a multilayered structure based on coordinate transformation theory and complementary media. There has been considerable research on invisibility cloaks such as the external cloak, which requires complex “anti-objects”, and closed cloaks of different shapes, in which the object enclosed is blind. Because all these are hard to realize in actual application, we apply a uniform layer to the whole construct into several parts in efforts to replace the ideal cloak with the aim to reduce complexity in actual fabrication. This multilayered cloak allows exchange of information without requiring “anti-objects”. All results were simulated and calculated in the Cartesian coordinate system and with the Comsol Multiphysics software. Electrical field simulations verified the efficiency of the designed cloak and the computed radar cross section (RCS) to illustrate the validity of this method and its efficiency in replacing the ideal cloak. |
